使用Kaniko的Tekton build Docker映像-请提供一个有效的路径到生成上下文中的Docker文件

Question

我是Tekton (https://tekton.dev/)的新手，我正在尝试

repository

• Build

• 克隆与Dockerfile的对接图像

我有一个Tekton管道，当我尝试执行它时，我会得到以下错误：

错误:解析dockerfile路径错误:请使用- Dockerfile为构建上下文中的dockerfile提供有效路径。

请查阅以下Tekton清单：

1. Pipeline.yml

apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
  name: clone-read
spec:
  description: | 
    This pipeline clones a git repo, then echoes the README file to the stout.
  params:
  - name: repo-url
    type: string
    description: The git repo URL to clone from.

  - name: image-name
    type: string
    description: for Kaniko

  - name: image-path
    type: string
    description: path of Dockerfile for Kaniko

  workspaces:
  - name: shared-data
    description: | 
      This workspace contains the cloned repo files, so they can be read by the
      next task.

  tasks:
  - name: fetch-source
    taskRef:
      name: git-clone
    workspaces:
    - name: output
      workspace: shared-data
    params:
    - name: url
      value: $(params.repo-url)

  - name: show-readme
    runAfter: ["fetch-source"]
    taskRef:
      name: show-readme
    workspaces:
    - name: source
      workspace: shared-data

  - name: build-push
    runAfter: ["show-readme"]
    taskRef:
      name: kaniko
    workspaces:
    - name: source
      workspace: shared-data
    params:
    - name: IMAGE
      value: $(params.image-name)  
    - name: CONTEXT
      value: $(params.image-path)    

1. PipelineRun.yml

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: clone-read-run
spec:
  pipelineRef:
    name: clone-read
  podTemplate:
    securityContext:
      fsGroup: 65532
  workspaces:
  - name: shared-data
    volumeClaimTemplate:
      spec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: 1Gi
  # - name: git-credentials
  #   secret:
  #     secretName: git-credentials
  params:
  - name: repo-url
    value: https://github.com/iamdempa/tekton-demos.git

  - name: image-name
    value: "python-test"

  - name: image-path
    value: $(workspaces.shared-data.path)/BuildDockerImage2  

这是我的存储库结构：

. . .
.
├── BuildDockerImage2
│   ├── 1.show-readme.yml
│   ├── 2. Pipeline.yml
│   ├── 3. PipelineRun.yml
│   └── Dockerfile
├── README.md

. . .

7 directories, 25 files

谁能帮我一下这里出了什么问题？

谢谢

Answer 1

我找到了问题所在。问题在于我提供道路的方式。

在kaniko任务中，CONTEXT变量确定Dockerfile的路径。默认值设置为./，并带有一些附加前缀，如下所示：

$(workspaces.source.path)/$(params.CONTEXT)

这意味着，workspaces的路径已经被追加了，我不需要像我在下面的image-path值中提到的那样追加该部分：

$(workspaces.shared-data.path)/BuildDockerImage2  

相反，我必须将文件夹名如下所示：

  - name: image-path
    value: BuildDockerImage2 

这解决了我的问题。
